It appears to fail to take into account the essential requirements of RFC3834: <https://datatracker.ietf.org/doc/html/rfc3834> in particular the exceptions listed in: <https://datatracker.ietf.org/doc/html/rfc3834#section-2> and ensuring that auto-reply envelope sender is the NULL sender: <>. So unless those requirements are built-in features of the filter syntax, this filter MUST NOT be used without appropriate modifications. -- Viktor. 🇺🇦 Слава Україні! -- ## subscription configuration (requires account): ## https://lists.exim.org/mailman3/postorius/lists/exim-users.lists.exim.org/ ## unsubscribe (doesn't require an account): ## [email protected] ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
